Compare and contrast proteins and carbohydrates. Consider how they are formed and their purpose/function inside a cell. 150-250 words.

Proteins and Carbohydrates each play their own important role in the body in our cells, as does each piece of our system plays a role in how we function and a making up a living being.  One way a protein acts is in insulin! Insulin is a tiny protein, you often hear of lack of insulin in diabetes patients, it’s captured on cell surfaces and delivers a message the amount of sugar available in the blood. Insulin is actually one of the most important proteins! (Info from rcsb.org) Proteins as Enzymes break polymers apart, which makes a chemical reaction. Proteins as hormones and receptors help with the communication of cells and the metabolism of glucose. That is just the surface out of all the things proteins do! There are defense proteins, you can assume what they do, and Storage Proteins like the white part of an egg hard-boiled. Proteins are made from polymers of amino acids these are called polypeptides. Folding and combining polypeptides gives rise to four different levels of protein structure. Carbohydrates or CH2O they are compounds of carbon, and carbon is the backbone of organic molecules! Carbon has four valence electrons. Unlike Proteins, carbon makes up the sugars. Some common ones are glucose “blood sugar, GA lactose in milk, and fructose in honey. Science can be found where you aren’t looking for it and in people there is a process behind how we are alive.  Starches are the polymers of glucose. A polymer is a chain of smaller molecules Glycogen is what animals use to store extra glucose by turning it into glycogen. One thing connects to another. Cellulose it is very common and has glucose in it. You can find almost pure Cellulose in wood, wool, and cotton. Carbohydrates are used for fuel! We breathe in carbon it’s in the air. Proteins and Carbohydrates are both very different, opposites, but we have to have both of them Proteins act as a messenger to the body, and a communicator and carbohydrates/carbon are used to power and fuel the body and many other things; through food, and air those are the primary actions of the two.
